i i i i improvements 111 sheet moistenlng devices,

My invention relates to new and useful and ismore particularly directed to the provision of a device for moistening the sides and valance flange portions ofsheets adapt ed to be folded to form envelops and, inclosedmessage sheets.

It is primarily the object of invention to provide an arrangement wherein sheets 7 disposed in superposed relation maybesuccessively moistened upon withdrawal from such superposed relation.

more specific object resides in the provision of a noistening device adapted tojbe associated with relatively large p les of sheets, and wherein the moisteningfoperation automatically remains effective upon reducing the height of the pile due to with drawal of sheets therefrom. I

A further object resides inthe provision ofa moistenin'g device possessingthe above advantages and which is adapted to simultaneously moisten the sides and valance flange ends of sheets of paper adapted to be folded to form combined envelops and message sheets.

With the above and other objects and advantages in view, the invention resides more particularly in the novel combination, formation and arrangements of parts hereinafter described and pointed out in the appended claims.

In the drawings:

Figure 1 is a plan view of my improved sheet moistening device.

Fig. 2 is a side elevational view of my improved moistening device, one end portion thereof in broken section as indicated by the line 2-2 of Fig. 1.

Referring now more particularly to the accompanying drawings, there is provided a bed plate 5 provided with a plurality of upstanding gage pins 6 for retaining a pile of sheets 7 on the bed. These sheets are of the usual type providing combined envelops and message sheets, and one end of each Specification of Letters Patent. Pmig imd 19 11 191 3 Application fiieaia aary 27,1917.

ing coating of paste 7 andthe adjacent side portions of the sheet are provided with longitudinally extending coatings of paste 7 A U-shaped water casing 9 is provided of such dimensions as to seat onthe paste carryingend portion of the pile of sheets and this casing is held'for vertical sliding movementby upstanding guide pins 10 slidable through outwardly projecting cars 11 on the arms of the casing. The top'portionsoftlie free ends of the arms of the casing are provided with transverse slots 12, and eX-' sheet 7 and to holdsaid wicks thereagaiiis't to properly moisten the. paste Coats" 7, a

weightbar 15is provided, the same having "its end portions downwardly offset to seaton the wicks, and apertured for the reception of upstanding guide pins 16 on the bed plate 5. The bight portion of the water casing is provided in its top with a longitudinal slot i 17 through which is passed the inner end of awide wick 18 secured by the set screws 19 and the outer poi't1on of this wickrests on the paste coated section 7 of the topmost sheet 7, beingproperly held thereaga'inst, by the downwardly oilset intermediate portion of a weight bar 20, the ends ofthis weight bar being apertured for the reception of up standing guide pins 21 on the arms of the casing.

The wicks are retained in a suitable moistened condition by capillary attraction, and thus upon successively withdrawing the sheets 7, the side and end coatings of paste are properly moistened, the weight of the casing 9 holding the pile of sheets in proper relation, in conjunction with the guide pins 6. a

While I have shown and described a preferred form of my invention adapted for a particular purpose, it is obvious thatother and perhaps simpler embodiments of my invention may be employed to meet differing conditions of use, without departing in any manner from the spirit of my invention, or exceeding the scope of the appended claims.

What is claimed 1. A moisteni'ng device comprising a bed plate, a fluid container connected therewith and adapted to have a pile of sheets'disposed thereadjacent, saidpile of sheets resting on the bed plate, a fluid distributing means connected with the container, and means movable independently of the container for continuously forcing the distributing means into engagement with the pile of sheets.

2. A moistening device comprising a bed plate,- a fluid container connected therewith, said bed plate being adapted to have a pile of sheets disposed thereon adjacent said con- 1 tainer, and a wick projecting fromthe upper portion ofthe container and depending at the sides thereofinto engagement with said pile of sheets, the fluid from the container being fed to saidsheets by capillary action. 7 3, A moistening devicecomprising a bed plate, a fluid container connected therewith for vertical movement thereabove, a wick projecting from the upper portion of the container and depending atthe sides thereof, and means, movable independently of the container for urging the free end of the wick toward the bedplate. I 7

L A moistening device comprising a bed for vertical movementand normally movable theretoward, a fluid distributing means projecting from the container, and means movable independently of the container and engaging the free end of the fluid distributing. means for forcing the same toward the bed plate, 1

' '5. A moistening device comprising a bed plate, spaced pairs of upstanding guide pins atthe sides thereof adapted to receive a pile I of sheets therebetween, a fluid container slidi c ies eat ge; y b main ably connected with one pair of guide pins, a wick; projecting from the upper portion of the container and depending at the side thereof, and a pressure bar slidably connect- 'ed with the other pair of guide pins and en gageable with the outer end of the wick.

6. A moistening device for envelop forming sheets comprising a bed plate,a U-shapcd fluid container connected therewith for vertical movement thereabove and adapted to rest on a pile of sheets on the bed plate, a fluid distributing member disposed longitudinally of the base of the fluid container and a'pair of fluid distributing members disposed at the free ends of the arms of the fluid container, said distributing means being adapted to engage said sheets.

7. A moistening device for envelop form- I ing sheets comprising a bed plate, a U-shapcd .7 fluid container connected therewith for ver tical movement thereabove, and adapted to rest on a pile of sheets on the bed plate, a wick projecting from the container between the legs thereof, and fluid distributing means at the free ends of the legs of the container, esaid wick and fluid distributing means be- .ing adapted to engage said sheets.

8. A moistening device comprising a bed plate, a fluid container connected therewith forvertical movement thereabove, a wick projecting from the upper portion of the container and depending at the side thereof, means movable independently of the container for urging the free end of the wick toward the bed plate to engage the articles thereon, and means for securing the wick to the container comprising a set screw threadedly passed into the container for binding the inner end of the wick to the bottom of the container.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.
